Queueing outside entrance to Co-operative Bank (7)
I believe the answer is:
incline
'operative bank' is the definition.
'incline' can be an answer for 'bank' (I've seen this before). I am unsure of the 'operative' bit.
'queueing outside entrance to co' is the wordplay.
'queueing' becomes 'in line' (to queue is to wait in line).
'outside' indicates putting letters inside.
'entrance to' says to take the initial letters.
The first letter of 'co' is 'c'.
'inline' placed around 'c' is 'INCLINE'.
(Other definitions for incline that I've seen before include "Be disposed to" , "Have tendency or slope" , "Gradient" , "Lean (towards)" , "Have a tendency to do or be something" .)
